Randomized Controlled TrialFeasibility of Protective Ventilation During Elective Supratentorial Neurosurgery: A Randomized, Crossover, Clinical Trial.
Traditional ventilation approaches, providing high tidal volumes (Vt), produce excessive alveolar distention and lung injury. Protective ventilation, employing lower Vt and positive end-expiratory pressure (PEEP), is an attractive alternative also for neuroanesthesia, when prolonged mechanical ventilation is needed. Nevertheless, protective ventilation during intracranial surgery may exert dangerous effects on intracranial pressure (ICP). We tested the feasibility of a protective ventilation strategy in neurosurgery. ⋯ Protective ventilation is a feasible alternative to traditional ventilation during elective neurosurgery.

Considering that growing population of very young children is exposed to general anesthesia every year, it is of utmost importance to understand how and whether such practice may affect the development and growth of their very immature and vulnerable brains. Compelling evidence from animal studies suggests that an early exposure to general anesthesia is detrimental to normal brain development leading to structural and functional impairments of neurons and glia, and long-lasting impairments in normal emotional and cognitive development. Although the evidence from animal studies is overwhelming and confirmed across species examined from rodents to non-human primates, the evidence from human studies is inconsistent and not conclusive at present. In this review we focus on new developments in animal studies of anesthesia-induced developmental neurotoxicity and summarize recent clinical studies while focusing on outcome measures and exposure variables in terms of their utility for assessing cognitive and behavioral development in children.

Effect of Albumin in Combination With Mannitol on Whole-blood Coagulation In Vitro Assessed by Thromboelastometry.
Albumin and mannitol may interfere with hemostasis, but their coinfluence is unclear. We aimed to determine the effects of albumin alone and in combination with mannitol or Ringer acetate (RAC) on hemostasis in crossover in vitro study. ⋯ In up to 15 vol% dilutions, albumin alone did not impair hemostasis in vitro, but in combination with mannitol or RAC coagulation was disturbed similarly at most concentrations. There was some significant additional effect with mannitol at certain concentrations. Our results indicate that coadministration of mannitol and albumin needs further study in vivo.

Endovascular Treatment of Acute Ischemic Stroke Under General Anesthesia: Predictors of Good Outcome.
The choice of anesthetic technique, general anesthesia (GA) versus Monitored Anesthesia Care, may impact the outcome of patients undergoing endovascular treatment of acute ischemic stroke (AIS). The aim of this study was to identify the factors associated with good discharge outcome in patients receiving GA for AIS. ⋯ These findings indicate the importance of ventilation management and extubation after endovascular intervention under GA in patients with AIS.

Comparative Study Observational StudyIntraoperative Neurological Monitoring With Evoked Potentials During Carotid Endarterectomy Versus Cooperative Patients Under General Anesthesia Technique: A Retrospective Study.
The best technique to evaluate contralateral carotid flow during carotid endarterectomy (CEA) is still debated; an accurate detection of efficient contralateral blood flow can avoid unnecessary shunt placement and its complications. The aim of this retrospective observational study was to evaluate and compare the safety and efficacy of general anesthesia with motor-evoked potential and somatosensory-evoked potentials (mSSEP and tcMEP) versus cooperative patients under general anesthesia (CPGA) technique for CEA. Primary outcome was the rate of technical failure. The procedural time and shunt incidence between the 2 neuromonitoring strategies were also analyzed. ⋯ mSSEP and tcMEP neuromonitoring was associated with less technical failure and procedural time than asleep-awake-asleep strategy. The evoked potential neuromonitoring may be an alternative technique to awake clinical assessment during CEA.
